Wanted to do something different. Had a set of carbon fiber wheels made. The design I made is a slightly modified Ferrari style and custom made center caps to match my calipers. I’m keeping the OEM wheels just so I could revert back to oem if I want. I had switched to MPS4 on the oem ones and they are great. BUT put Cup2s on the CF and now the car is super sticky without any spin at all! The tires do have to warm up a bit but when they do they stick like glue.

Nice! How about a side profile shot so we can see how they 'tie in' with the car...thanks.
Weight savings amount?

It’s really a great looking car!👍
Weight savings over 50% but it was the look that got me with the carbon package exterior.
thanks. did you weigh OEM and new wheels? i was interested in actual difference in pounds and ounces

I was guessing over a 50% reduction in weight, at least.
I did a similar comparo with my GT's stock Neptunes, (10.5x20 with a 305 series Michelin tire) vs. a considerably wider aftermarket HRE wheel, (20x12 with a 345 series tire). The much wider HRE still had a significant weight reduction over the smaller Neptune.
Those carbon fiber wheels are even more ridiculously lighter!

If I order the MC20 Folgore, I am considering ordering custom wheels for summer to save weight and increase range.
I got forged aluminum wheels for my BMW iX and it has made a big difference on range, and would get forged magnesium for my MC20 which would cost around $6K for a set of 4, and save 30% on rotational mass over the OEM forged aluminum wheels not including carbon brakes.
How much were the carbon fiber wheels?
Where did you get them?
How fragile are they compared to OEM wheels?
BTW the carbon wheels look great!!!

I can get the weights of the new wheels with tires when I go for yearly inspection next month as the wheels have to be removed for state brake inspection. I can weigh the OEMs as they still have the entire set up intact TPMS, tire, and wheel. I will post both once I get that done.
Bucci Composites Faenza, Italy they make great wheels. You can get wheels from Carbon Revolution and ESE. I was told they don’t do custom design but will make them to fit the MC20.
13.44 lbs per in weight savings.
About weight reduction ( or gain ) from wheels ; the internet is full of junk opinions and claims from car owners who supposedly calculated the rotating mass weight effect on static weight with “results“ varying form a low of 2x to as high as 10x. The latter sounded borderline absurd to me , whereas 2 x or 3 x sounded more reasonable . So I searched car publications articles on the topic , but only found a couple which indicated an average impact of 5:1, with the range moving from off the line acceleration ( higher ratio ) to rolling acceleration from 100 mph + . But here’s a summary excerpt from a Porsche publication , referring specifically to a GT3RS performance effect :
”for wheels, every pound you shave off your rotating weight is equivalent of 8.4 pounds removed from static weight. So shaving 11.6LB off your wheels setup is equivalent of removing 97.44LB off the chassis of your car. “
I generally give Porsche a lot of credibility, but somehow a 8.4 : 1 ratio seems extraordinary . So if you add bigger wheels ( and heavier tires ) the combo weight impact seems very hefty ..vice versa if you reduce the rotating mass weight . So 13.44 per wheel weight reduction , equals 451.5 lbs removed from your car ? 😲😳. It’s like shoving your sumo wrestler passenger out of the car ( not that I would not recommend shoving any sumo wrestler ..) 😜

Great info, especially for racers. Getting groceries though, not so much. 🤣About weight reduction ( or gain ) from wheels ; the internet is full of junk opinions and claims from car owners who supposedly calculated the rotating mass weight effect on static weight with “results“ varying form a low of 2x to as high as 10x.

Exactly ! And particularly in all lightweight true sports cars . In our heavy GTs land-yachts, meh.. not so necessary .. aesthetics are more important there , IMHO .
